Most SME organisations are still running critical Microsoft systems that no longer receive security updates, or are about to lose support entirely.
This may not seem urgent, because these systems don’t simply stop working. But they do become immediately vulnerable.

Windows Server 2012 reaches its final Extended Security Update Expiry.
After this date:
- No patching
- No support
- No fallback
At the same time, multiple core Microsoft systems reach end of support.
The countdown is on until your systems are vulnerable.

This is not simply an IT Issue. It’s a very real business risk.
Unsupported systems expose unpatched vulnerabilities
Failure to meet regulatory frameworks (GDPR, FCA, NIS2)
Breaches and downtime create significant cost and disruption
Most organisations are planning migration. But migration timelines don’t necessarily match security risk timelines. That leaves a gap:
Legacy systems still live
Security risk increasing daily
No structured protection



- Full assessment of your environment
- Mapping against Microsoft deadlines
- Clear risk profile
- Actionable next-step roadmap.
